How to watch Immutable Law of First Love: Season 1 (2015) on Netflix Belgium!

Hae-joo is working part-time at night at a coffee shop, when her homeroom teacher Jong-gu comes in and orders a cup of coffee.

Jong-gu has a complex expression on his face. He thought he had given all his heart to Yeo-ri but he can't get Ha-na out of his head.

Jong-gu takes Ha-na home in his car. Before entering her home, Ha-na runs into Hae-joo who makes another passionate confession of love.

After meeting Yeo-ri, Jong-gu can't stop thinking about her.

Jong-gu hangs around Yeo-ri's office and shouts out through a megaphone to get her back. He manages to meet her and confesses that he has missed her.

On their first date, Yeo-ri is taken aback to see Jong-gu carrying snacks, kimbap, toast and many other refreshments in his bag.

Ha-na holds back her tears. She tries to save Hae-joo from bullies and gets scratched. Ha-na sobbingly recalls the day when she first met Jong-gu.

Jong-gu roughly kisses Ha-na. He says this is the sort of treatment she should expect from him, and that she should thus leave him. He walks away.

Back home, Jong-gu desperately calls out Yeo-ri's name. The resentful Yeo-ri, however, is hard on him, saying he has no respect for his relationship.

Ha-na and her friends manage to find Jong-gu walking into the water and frantically try to stop him.

At the beach, thanks to fate, Jong-gu and Yeo-ri meet again and realize how much they still love each other.
